Description

Technical Field

[0001] The utility model relates to the technical field of sound boxes, in particular to a foldable combined sound box. Background Art

[0002] A combination speaker generally includes a main speaker and a slave speaker. In the existing combination speaker, the main speaker and the slave speaker are respectively used to play left and right channel audio signals to form a stereo effect. The combination speaker is used in a wide range of places, mostly in teaching and lectures. The main speaker and the slave speaker are mostly separate individuals. Therefore, the way the device is used in combination is related to the position and angle between the main speaker and the slave speaker.

[0003] Most of the existing combined speakers are separate entities without any connection between them. Therefore, during use, due to their small size, they are inconvenient to store. At the same time, since they are not connected to each other, it is easy for differences in signal reception effects to occur. To address the above problems, we have launched a foldable combined speaker. Utility Model Content

[0022] The following will be combined with the attached Figures 1 to 4 The utility model is described in detail, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a foldable combined sound box through improvement. Figure 1-Figure 4 As shown, it includes a speaker storage box 1, a main speaker 2 is arranged above the inner cavity of the speaker storage box 1, and sub-speakers 3 are installed at both ends below the main speaker 2. Folding rails 4 are evenly distributed outside the main speaker 2, and heat dissipation boxes 12 are arranged at both ends of the inner cavity of the speaker storage box 1; the folding rail 4 includes a spherical steering area 401, the spherical steering area 401 is opened inside the folding rail 4, and a directional movement area 402 is opened on the side opposite to the spherical steering area 401; both sides of the inner cavity of the speaker storage box 1 are provided with storage components for storing the main speaker 2 and the sub-speaker 3. Connecting rods 5 are evenly distributed on the top of the sub-speaker 3 near the center of the inner cavity of the speaker storage box 1, and a connector 6 is fixedly connected to the top of the connecting rod 5. The center of the connector 6 is set as a partial sphere, and the front and rear sides of the connector 6 are set as a cube, and the front and rear sides and the arc surface at the center of the connector 6 are located on the spherical surface of the same sphere.

[0024] In this embodiment: first, when not in use, the main speaker 2 and the secondary speaker 3 are stored inside the speaker storage box 1. At the same time, when inside the speaker storage box 1, the main speaker 2 and the secondary speaker 3 can also be turned on for operation and use, and heat is dissipated through the heat dissipation box 12. The main speaker 2 and the secondary speaker 3 are connected by a connector 6 and a connecting rod 5 embedded in the folding rail 4. The spherical turning area 401 and the front and rear sides and the arc surface at the center of the connector 6 are located on the spherical surface of the same sphere, so that the angle of the secondary speaker 3 can be adjusted under the premise that the main speaker 2 and the secondary speaker 3 are always connected. Since the front and rear sides of the connector 6 are set as a cube, the secondary speaker 3 can move horizontally with the directional movement area 402 as a trajectory.

[0025] In the first embodiment, since the internal space of the speaker storage box 1 is small, when the main speaker 2 and the secondary speaker 3 are running inside the speaker storage box 1, the heat dissipation space is small, so the heat dissipation effect is poor. The specific operation is as follows:

[0026] like Figure 1 and Figure 2 As shown, the heat dissipation box 12 is rotatably connected to the heat dissipation fan 8, and the side of the heat dissipation box 12 close to the inner center of the speaker storage box 1 is set as a hollow mesh. Heat dissipation grooves are equidistantly opened inside the two ends of the speaker storage box 1, and the heat dissipation grooves are set as a 45-degree inclined structure.

[0027] In this embodiment: through the rotation of the heat dissipation fan 8 and the use of the heat dissipation slot, the heat dissipation inside the speaker storage box 1 can be accelerated, so that the heat dissipation efficiency is improved. At the same time, the heat dissipation slot is set to a 45-degree inclined structure, which can prevent dust from accumulating inside the heat dissipation slot;

[0028] In the previous embodiment, since the main speaker 2 and the secondary speaker 3 are taken out from the speaker storage box 1 for use in most cases, it is necessary to ensure that the main speaker 2 and the secondary speaker 3 are easily stored back into the speaker storage box 1 after use. The specific operation is as follows:

[0029] like Figure 1 and Figure 3 as well as Figure 4 As shown, the storage assembly includes a moving bar 9, which is evenly distributed on the top of the main speaker 2 and the bottom of the secondary speaker 3, and the moving gears 10 are evenly distributed inside the moving bar 9. A transfer platform 11 is fixedly installed on both the upper and lower sides of the inner cavity of the speaker storage box 1, and the inside of the transfer platform 11 is evenly provided with moving grooves, and the inside of the moving grooves is fixed with a moving rack 7.

[0030] In the present embodiment: firstly, through the action of the movable bar 9 and the movable groove, the position of the main speaker 2 and the secondary speaker 3 stored in the speaker storage box 1 can be limited, and at the same time, through the cooperation of the movable rack 7 and the movable gear 10, the process of storing the main speaker 2 and the secondary speaker 3 in the speaker storage box 1 is smoother.

[0031] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
